fix: resolve TypeScript errors in reconciler and mtcute-adapter

- Update MTCute imports to use correct types from @mtcute/tl
- Fix MessageEntity construction with proper discriminated union types
- Fix callback query data handling for string/Uint8Array
- Update inline keyboard markup structure
- Fix reconciler host config type issues
- Add @ts-expect-error for complex React reconciler types

Note: One persistence mode test is still failing - static content
in formatted elements loses children on re-render. This appears
to be a complex issue with how React's persistence mode handles
child reconciliation.
